Chapter 385 "Xi soil" fights against the Flood
Captain Huang was right. This kind of matter is related to the safety of dozens of millions of people. Naturally, it cannot be just the statement of his commander. Can be decided.
But even so, the determination shown by him and other commanders and fighters involved in the disaster relief still had an impact.
At noon the next day, after a whole morning of discussions, the flood control directorate finally officially issued the instruction "No flood diversion will be carried out until the water level rises to 45.3 meters."
But just in case, the transfer of people in the flood diversion area still cannot be stopped.
With such an instruction, tens of thousands of PLA commanders, militiamen, and cadres and masses involved in rescue operations on the entire Jiangling Embankment were all mobilized to prepare for the upcoming sixth wave of floods!
......
Also at a critical juncture, there is Xunyang further downstream.
Due to special terrain factors, this city located next to Poyang Lake has borne the brunt of previous Yangtze River floods.
Although the local rainfall is not heavy, when the upper and middle reaches of the main stream and tributaries flood one after another, and begin to interact and overlap with each other, the risk of flooding is actually more serious than in areas with heavy rainfall in the upper reaches.
After the decision not to divert floodwaters from Jiangling was made, the pressure of the entire Yangtze River Basin gathered here in a short period of time.
There is no flood discharge area designed in advance, so there is no other choice but to resist.
At the same time, because there is no flood discharge area, there is no place to focus on in the entire Xunyang section of the Yangtze River embankment.
This is definitely not a good thing -
Everyone who has taken the exam knows that if there are no key points, it means it is all about the key points.
The Xunyang section of the dyke was not expected to withstand such a large flood. As the previous rounds of flood peaks came one after another, it was still unable to fully withstand the increasingly high water levels.
The tens of thousands of rescue troops looked like a lot, but if they were to be spread out evenly across hundreds of kilometers of embankment like beans, I'm afraid they wouldn't be able to hold on if there was any problem.
So we can only concentrate on staying at the garrison not far away.
And because the stratosphere above Gan Province does not meet the required meteorological conditions, and Zhejiang University does not have any on hand. There is a second set of relay communication equipment, so the information transmission situation here is much worse than that in the Jiangling area of Hubei Province.
Fortunately, the local weather is okay, so helicopters from the Army Aviation Force continue to take off, firstly to monitor the situation, and secondly, to be ready to respond to possible communication interruptions.
"Report, there is a collapse between gates 4 and 5 of the embankment!"
In the local defense frontline headquarters, an anxious voice suddenly sounded.
The most worrying thing happened.
“The current width of the breach is 60 meters, but there is a tendency to expand to both sides.”
Liao Xinmin, the local head of the general defense department, is naturally far inferior to Niu Maosheng of the national defense chief, but he The determination at the critical moment is not bad at all:
"Explain the situation to the People's Liberation Army troops and ask for reinforcements. The remaining people, follow me up the embankment!"
The breach at the scene was like the mouth of a dragon, with the torrential river water pouring down and heading towards the urban area of Xunyang.
And there, there are 4.5 million people who have nowhere to move.
The 60-meter wide breach itself will not make the situation out of control, but as the saying goes, a thousand-mile dike is destroyed in an ant nest. If such a breach cannot be controlled in a short time, it may even trigger the entire dike. collapse.
This hole must be blocked.
The specific method of blocking will have to be decided by experts from the water conservancy department.
But no matter what method is used, the first step must be to reduce the flow rate and flow rate.
Otherwise, any building materials and construction equipment will not be able to operate normally in the roaring river.
“Have you been deployed according to the emergency plan?”
Liao Xinmin asked the on-site staff next to him.
"We had already deployed it when the bubble phenomenon was discovered before, but the flood level in our plan is far different from the current situation. It is a drop in the bucket."
The latter's body and face It was almost completely covered with mud and water, and his tone was also full of anxiety:
“Just now, shipowners from near Poyang Lake rushed over spontaneously and scuttled 8 inland river ships with a total of 10,000 tons near the breach. The coal ship has played a small role, but the water flow is too fast, especially the bottom of the ship can still pass a large amount of water, causing the position of the sunken ship to continue to change. If new blocking items cannot be filled in, it may not be too long. Time will be washed away!”
The cadres and masses participating in the rescue on the shore are throwing in all the gravel, rubble, and coal they can collect.
But even a sunken ship with tens of thousands of tons cannot guarantee complete stability, let alone these small things, which disappear without a trace almost as soon as they are thrown into the water.
Just when everyone was almost helpless, a shout came from not far behind.
"The People's Liberation Army is here, the People's Liberation Army is here!"
Liao Xinmin turned around suddenly and saw a convoy of hundreds of trucks on the road in the distance, like a long winding queue, heading towards Drive in the direction of the embankment.
When the People's Liberation Army comes, there is hope.
“Quick, prepare the relevant information and the current situation of the breach, and do your best to cooperate with the comrades in the army in disaster relief!”
The first person to lead the team was Wang Hong, the commander of the 2nd Regiment of the 1st Division of the Jinling Military Region.
After listening to the brief report, he went to the breach to check the situation in person.
“We have tried shipwrecks, gravel, and sandbags, but they were all unable to be fixed and were quickly washed away.”
Liao Xinmin wiped the confusion on his face. Is it sweat or river water? He said to Wang Hong who was looking around to observe.
“Normally, in this case, blocking the mouth alone is not enough. You need to drive wooden piles and steel bars into the river bed to form a cage-like structure, and then throw gravel bags and sandbags inside. ”
Before setting off, he had already consulted with senior superiors with relevant experience, so he had already made preparations in this regard.
“But how can we push things into such a large amount of water?”
Liao Xinmin was dumbfounded when he heard this answer.
If you want to construct in water, you need to use blockers to reduce the flow speed. And to reduce the flow speed, you need to drive wooden piles and steel bars into the water first?
“Leave it to us.”
After Wang Hong finished speaking, he asked for a wrist-thick rope from the staff behind him, tied it around his waist, and then took the loudspeaker used for shouting from Liao Xinmin.
“All cadres from the company and above, come out!”
Soon, the hundreds of selected commandos tied themselves into several strings with ropes and stayed on the shore. The person held on to the other end of the rope.
Immediately afterwards, Wang Hong took off the hat on his head and jumped into the river first.
With the obstruction of several human walls, the turbulent water finally slowed down slightly.
Others who came up with reinforcements began to throw sandbags into the middle of the human wall.
Although most of it will still be washed away, at least it has begun to have some effect.
It is impossible for trucks transporting supplies to drive directly onto the embankment, so the last section of the road can only be completed entirely by manpower.
Half an hour later, the first wooden pile was successfully driven into the bottom of the river bed, finally giving the nearby crumbling human wall a new support point... Although the situation has progressed, the efficiency Still not high.
Moreover, the risk is high.
It was fine when everyone had plenty of energy at first, but as time passed, everyone's energy was rapidly drained from being immersed in the flood for a long time.
Some of the weaker warriors were almost washed away.
Of course, the people on the shore and in the water are also rotating, but due to manpower shortage, even on the shore, they have to be responsible for carrying disaster relief materials, which cannot guarantee adequate rest...
Time passes like this. It took two days.
The breach was initially under control, but the flood was still pouring outward at a flow rate of more than 130 cubic meters per second and a velocity of 5 meters per second.
According to the plugging plan, after the breach is initially controlled, a half-moon-shaped cofferdam should be formed in the area to prepare for the subsequent filling and embankment work.
But because Wang Hong and others used ropes to secure themselves when they first went down, it was really difficult to make the cofferdam into a half-moon shape.
It can only expand outward little by little on the basis of a straight line.
However, after two days of continuous high-intensity work, the commanders and fighters of the three regiments participating in the flood fight had almost reached their limit.
Many people have fallen into coma or even gone into shock due to overexertion, and have been sent to makeshift field hospitals nearby.
The on-site commander was heartbroken, but there was nothing he could do.
In fact, he has already sent his own sons who are currently serving as company commanders.
A division has no reserves.
"Deputy Commander Dong, the leader of the 2nd Regiment just reported that a new batch of strange relief supplies will be sent later."
The deputy chief of staff of the Jinling Military Region came over and whispered the report in his ear.
“Strange?”
Lack of sleep for a long time caused the commander-in-chief to be stunned for a moment before reacting:
“Let’s go and have a look.”
When When he arrived at the disaster relief supplies distribution center near the embankment, he saw Wang Hong communicating with a man in casual clothes opposite.
Next to it were two large bags unloaded from the car.
Top material.
One of them had been opened and inside was...
Something that looked like a sack.
“What’s going on?”
"Reporting to the commander-in-chief, this is a new batch of disaster relief materials. Comrades from the Zhejiang Provincial Bureau of Science and Industry are introducing us to the precautions for use."
Wang Hong came up, saluted, and replied.
“That’s all?”
The commander-in-chief picked up a corner of a bag from the side and weighed it.
It is flat, takes up almost no space, and seems to weigh less than one-tenth of a sandbag.
The casually dressed staff member next to him nodded:
"Yes, this is a flood-proof expansion bag that we rushed to produce. The first batch now totals 10,000, and there will be more in the future. It is being produced and transported.”
“Although it looks small now, as long as it is thrown into the water, it will become slightly larger than a standard sandbag in ten seconds and the weight is about the same. It greatly reduces the physical burden on the soldiers.”
“In addition, the vehicle also has prefabricated steel plate beams, which can be assembled with bolts when transported to the site. Their ability to resist water flow impact is much stronger than ordinary steel cages. ..."
Hearing this last sentence, the commander-in-chief thought of the young faces that had fallen in front of him in the past two days, his eyes turned red, and he quickly turned his head slightly.
"Captain Wang, let your troops try it!"
"Yes!"
In fact, after hearing the other party's introduction, Wang Hong was still a little doubtful.
The main reason is that this description is so amazing.
When people encounter particularly big good news, their first reaction is often to doubt its authenticity.
But anyway, these expansion bags are very easy to carry, and he can carry a dozen of them by himself, so it doesn't hurt to give them a try.
In case it is useful.
He called a few people and took out a total of 100 expansion bags from the first waterproof bag.
The sharp-eyed warrior noticed that the word "Xi soil" was printed on the surface of the bag.
Wang Hong has read some books and knows that this seems to have something to do with the legendary Dayu.
The jackpot is pretty good.
But if we dig deeper, Dayu and his old man used dredging method to control the water, and now this thing is obviously used to block...
The group quickly returned to the breach. nearby.
Wang Hong personally threw the first expansion bag into the water flow.
Then, amidst the stunned expressions of several people, this thin bag that was expected to be washed away in an instant actually expanded rapidly as the person from the Science and Industry Bureau just said.
Finally, it was blocked by two wooden stakes set up behind it, which perfectly acted as sandbags.
"TMD...is it really useful?"
Wang Hong's shock instantly turned into ecstasy.
Even if we do not consider the steel plate beams that have not yet been tested, this expansion bag alone is enough to increase the rescue efficiency by 10 times!
“Quick, send someone to move some more, we will speed up the progress!”
After reacting, he directly threw the remaining ten expansion bags into the water, then turned around and shouted an order to the staff officer behind him.
"In addition, according to this efficiency, we can block the hole before nightfall today and tell the engineers to prepare to fill the pond and consolidate the embankment!"
